Abstract (en)
[origin: EP0138286A1] A method of preparing a carbonaceous pitch, including the steps of: subjecting a raw material oil to thermal cracking conditions while removing cracked, light hydrocarbon components to obtain a pitch product containing at least 5 weight of mesophase and not more than 10 weight of light hydrocarbon components with a boiling point at 60 mmHg (absolute) of 300 DEG C or less and having a softening point of between 140 and 220 DEG C, the raw material oil being composed mainly of a residual oil which has a boiling point of 350 DEG C or more and which is derived from a naphthene base and/or intermediate base petroleum crude; and removing the mesophase from the pitch product to obtain a substantially mesophase-free carbonaceous pitch. The mesophase-free pitch may be converted into carbon fibers in the conventional manner.
